Prestonia
From TPU Reference
rochiletoz Prestonia was the successor to Foster. Just like Foster was based on Willamette Prestonia was the counterpart of Northwood. It was produced at 0.13µ and came with both the original 400 MHz FSB and an increased 533 MHz FSB. Early versions with a 400 MHz used Socket 603 while later 400 MHz FSB models and all of the 533 MHz FSB models used Socket 604. Clock speeds were also updated, models now ranged between 1.8 GHz and 3.06 GHz. Not only did the clock speeds increase, cache was also double to 512 KB L2 and Hyperthreading, which was introduced in Foster MP was added in an improved form. A dual processor Xeon could now handle up to four threads at once. Besides performance increases due to all these improvements Intel also dropped the Rambus requirement, Prestonia could run with cheaper DDR modules. The chipsets still required ECC modules though. Prestonias multiprocessor brother is called Gallatin.
Prestonia features:
- 1.8 - 3.06 GHz Clock
- 8 KB L1 data + 12 K L1 instruction cache
- 512 KB L2 cache
- Hyperthreading
- MMX, SSE, SSE2
- 0.13µ die
Overclocking nirvana
With enthusiasts everywhere overclocking their desktop systems Asus decided to bring this group of users the PC-DL motherboard. The PC-DL was a dual socket Xeon board based on the i865 chipset and very similar to their P4C800 series. Using a cheaper desktop chipset allowed the Xeons to be overclocked like their Pentium 4 brothers and allowed cheaper non-ECC RAM to be used. In addition this board came at a lower price than any workstation or server class board making Prestonia an interesting choice for the enthusiast. Several models were actually capable of running at a FSB of 800 MHz, which put a single chip on par with the 800 MHz Northwood, though there are two. To praise this board and discuss it's possibilities some people made a fansite: http://www.datamine.tk
